There is no universal "Download Center" for this device because ISPs maintain strict control over the firmware. However, here are the three most reliable methods to install a "hot" update.
The Huawei HG8145X6 is a powerful but quirky device. Official ISP updates are your safest bet. Unofficial community firmware carries significant risk but unlocks customization. Always your original configuration before attempting updates and maintain a TTL serial console connection as a recovery method.

This is the most insidious cause. The HG8145x6 communicates with the upstream OLT (Optical Line Terminal) via OMCI. In “hot” firmware branches, Huawei altered the Dying Gasp and Keep-Alive intervals from 10 seconds to 100 milliseconds to satisfy carrier QoS metrics. Consequently, the ONT’s management processor is handling 10 times the interrupt requests per second. This doesn't improve latency; it merely cooks the optics. The SFP+ module’s laser driver overheats, raising the base temperature of the entire board.
Based on community testing from forums like DSLReports, Huawei-Huawei, and GitHub, here’s how major firmware versions behave regarding heat:
: Using remote management systems, the new firmware is delivered to the HG8145X6 ONT. The device automatically performs the upgrade, usually without manual intervention.
